Abstract
Current study deals with the in vitro antioxidant of gold nanoparticles using aqueous extract of Curucuma longa. The antioxidant activity was evaluated using DPPH radical scavenging assay, Nitric oxide radical scavenging and Hydrogen peroxide scavenging assay. DPPH radical scavenging activity, Nitric oxide radical scavenging and Hydrogen peroxide scavenging assay of synthesized gold nanoparticles increased in a dose dependent manner as compared to Curcuma longa and ascorbic acid the standard reference used. This result confirmed that Curcuma longa is a potential biomaterial for synthesizing gold nanoparticles which can be exploited for its antioxidant activity.
